Starting November 1, 2025, all Android apps will need to support 16 KB memory pages.

Google Play enforces a new binary requirement for submissions that target Android 15+. This change affects both new releases and updates and aims at measurable gains in app performance across devices.

Teams that use only Kotlin and Java often face little work. Projects with native C/C++ code or third‑party SDKs usually need rebuilds or config tweaks. Expected benefits include faster launches, better battery life, quicker camera starts, and faster system boot times.

Act early: evaluate toolchains, run APK Analyzer and Lint checks, and test on emulator targets. Noncompliant binaries risk blocked releases and reduced visibility on the Play Console.

Key Takeaways

  • Enforcement begins November 1, 2025 for Google Play submissions targeting Android 15+.
  • Switching page size yields faster launches, better battery, and quicker camera and boot times.
  • Pure Kotlin/Java projects often require no changes; native builds likely need updates.
  • Use Android Studio tools and Play Console checks to validate compliance.
  • Contact www.iottive.com or sales@iottive.com for upgrade help and compliance packaging.

Why this change matters now: performance gains, compliance, and the Android 15 shift

Shifting to a larger page layout unlocks real performance wins across boot, launch, and camera workflows.

From 4 KB to 16 KB: what page size means for your app

Android 15 is page-size-agnostic: devices can run with either 4 KB or larger pages while correctly built binaries run across both.

A larger page reduces bookkeeping in the MMU, lowers TLB misses, and trims CPU time spent on mapping management. That improves overall system responsiveness and shortens common critical paths.

Documented gains: faster launches, better battery, quicker camera, speedier boot

Measured outcomes from Google tests show device performance boosts of roughly 5–10% on larger page configs. Teams can cite up to 30% faster app launches in some cases, ~3% average faster launches, ~4.56% reduced power draw, quicker camera starts (~4.5–6.6%), and about 0.8s faster system boot.

Compliance is opportunity: enabling larger page support unlocks these gains on modern devices while remaining compatible with 4 KB installations. If you need help quantifying wins or preparing a rollout, contact www.iottive.com or email sales@iottive.com.

Android apps will need to support 16 KB memory pages: what the Google Play deadline requires

From the November cutoff, any new release or update targeting android 15+ must meet Play Console binary checks before publication.

Scope of enforcement:

  • Effective November 1, 2025, Google Play rejects uploads for new submissions and updates that do not meet the page sizes requirement when targeting android 15+.
  • Use the Play Console app bundle explorer to spot non-compliant artifacts early and avoid blocked updates.
  • Projects with native code and prebuilt libraries face the highest risk and often require rebuilds or updated binaries.
  • Third-party sdks that include native libraries must confirm timelines for compatibility; React Native, Flutter, and Unity already provide aligned builds, while Unreal Engine is still finishing support.

Action now: verify dependencies, add a compliance gate to release criteria after October 2025, and engage vendors if their binaries are not aligned.

Plan your upgrade: a how‑to roadmap for developers and teams

Create a cross-functional plan that ties testing targets and release gates to firm deadlines. Set a migration owner and form a squad with engineering, QA, release, and vendor leads. This keeps responsibility clear and timelines realistic.

Key scheduling actions

  1. Set milestones that finish weeks before the November 1, 2025 cutoff.
  2. Upgrade toolchains early: AGP 8.5.1+ and NDK r28+ are recommended.
  3. Audit code for page-size assumptions and list required changes.

Create a dual-environment test matrix

Build tests that cover both 4 KB and 16 KB environments across smoke, regression, and performance suites. Include on-device checks and emulator targets so you catch platform differences early.

Vendor coordination and release gates

Inventory native libraries and rank their risk. Ask vendors for 16 KB-ready builds and log fallbacks if timelines slip.

Assess your app today: find native code, page size assumptions, and risks

Start by scanning your release artifact for native binaries that might break under larger page configs. Open the bundle in APK Analyzer and note each .so file at the module level. This gives a quick view of compatibility markers and risky libraries.

Use APK Analyzer and Lint

APK Analyzer shows embedded modules and marks 16 KB readiness. Run Android Studio Lint to catch non‑aligned libraries early. Catalog third‑party binaries and map vendor compatibility notes.

Spot hardcoded assumptions

Search repositories for PAGE_SIZE, 4096, and alignment directives. Replace fixed values with runtime queries like getpagesize() or sysconf. Audit mmap, ashmem, and file mappings for implicit boundaries that affect page tables and reclaim paths.

Next steps: build a risk register, prototype a small harness for native allocation paths, and plan targeted testing runs. If internal expertise is limited, contact us for a rapid assessment and remediation plan at www.iottive.com or sales@iottive.com.

Upgrade your toolchain: build and package with 16 KB alignment

A consistent build pipeline is the fastest path to compliant, aligned binaries. Start by making packaging defaults part of your release checklist so every artifact meets Play Console checks before an upload.

Adopt Android Studio + AGP 8.5.1+

Android Studio with AGP 8.5.1+ applies 16 KB alignment for uncompressed shared libraries by default. That reduces manual steps and keeps packaging predictable across builds.

Move to NDK r28+ or set linker flags

NDK r28+ compiles with 16 KB alignment across ABIs. If older toolchains persist, add linker flags such as -Wl,-z,max-page-size=16384 and, where required, -Wl,-z,common-page-size=16384. Check build logs for the applied size and page markers.

Rebuild native modules and verify artifacts

Rebuild every native code module, JNI bridge, and prebuilt library. Audit third‑party sdks and ask vendors for updated builds if their libraries lag.

  • Confirm alignment with APK Analyzer and command-line checks.
  • Document evidence per release for compliance audits.
  • Integrate reproducible steps in CI so alignment is enforced for all branches.

Fix your code for page‑size agnosticism

Make your low-level code agnostic: query the system for the actual page value at startup and use that everywhere. Replace fixed literals and document the changes so future edits do not reintroduce assumptions.

Replace hardcoded 4096 with runtime queries

Remove constants like 4096 and PAGE_SIZE in native modules. Use getpagesize() or sysconf(_SC_PAGESIZE) and cache the result.

Audit mmap, allocators, and IPC

Review mmap and file mapping offsets so they use the runtime value for alignment. Check custom allocators and arenas for alignment logic that assumes a fixed boundary.

  • Validate ashmem, shared memory, guard pages, and signal handler alignment.
  • Add unit and integration tests that run with both 4096 and 16384 values.
  • Consider static analysis rules that flag hardcoded page literals in native code.

Need help? Engage iottive for a focused audit and patch plan to reach page‑size agnosticism quickly and safely. Contact www.iottive.com or sales@iottive.com.

Test in a 16 KB environment: emulator, real devices, and remote labs

Validate early and often. Set up a controlled test environment that covers emulators, local devices, and remote labs before any release. This catches alignment errors and performance regressions early.

Use Android Emulator targets (arm64 and x86_64)

In android studio, create emulator images configured for the larger page alignment on both arm64 and x86_64. Run smoke and performance checks there first.

On‑device validation

On supported Pixel 8/8 Pro and newer devices (Android 15 QPR1+), toggle the developer option between 4 KB and 16 KB and confirm with adb shell getconf PAGE_SIZE.

Leverage remote labs

Use Samsung Remote Test Lab to broaden coverage across OEM builds and regional variants. Remote devices help replicate real‑world conditions you may not have locally.

  • Build a test plan: list expected outcomes for login, camera, media, storage, and cold/warm launches.
  • Capture evidence: logs, performance metrics, and alignment errors for each run.
  • Automate: environment setup scripts and data seeding so runs are repeatable and fast.
  • Include negative tests: check buffers and alignment‑sensitive operations for hardcoded assumptions.
  • If needed, engage iottive to provision environments, author plans, and triage issues at www.iottive.com or sales@iottive.com.

Verify dependencies: third‑party SDKs, engines, and libraries

Start by mapping every third‑party library and engine inside your build so nothing slips through a release gate.

Inventory analytics, A/V, ML, networking, and game engines. Note versions, ABIs, and whether vendors supply prebuilt binaries.

Update to 16 KB‑ready SDKs

React Native and Flutter offer compatible releases today. Unity also provides aligned builds, and Vivox reports readiness for voice features.

Monitor Unreal for its official timeline and plan fallbacks if a vendor misses delivery dates.

Coordinate with vendors for compliant binaries

Ask each vendor for a statement of compliance and artifact details: ABI targets, alignment flags, build toolchain, and minimum OS level.

“Request vendor statements and verify artifacts with APK Analyzer and Lint before gating a release.”

  • Validate updated libraries with APK Analyzer and Lint for alignment and packaging regressions.
  • Create a vendor tracker with delivery dates, test results, and fallback options.
  • Run targeted tests for voice, streaming, and camera pipelines that are sensitive to mapping behavior.
  • Check transitive dependencies inside SDK bundles; nested libraries must be verified too.
  • Gate releases: add a dependency sign‑off step so non‑compliant artifacts cannot ship.

Automate checks in CI: lint, alignment, and compliance gates

Automating artifact checks prevents last‑minute release blocks and saves engineering hours.

Start by integrating tools that flag misaligned binaries and hardcoded page values early. Add Android Studio lint as a CI step so native libraries and suspicious code patterns surface in pull requests.

Integrate Android Studio Lint and command‑line scripts

Run lint with a strict ruleset and fail on alignment warnings. Combine that with command‑line scripts that validate packaging flags and parse artifact headers for correct page alignment.

Fail builds on non‑aligned libraries and PAGE_SIZE violations

Create a compliance gate that fails builds when any binary, library, or code heuristic triggers. Automate APK Analyzer or equivalent tooling to emit machine‑readable alignment reports.

CheckActionCI Outcome

Measure the wins: launches, battery, camera, and system performance

Quantify end‑user impact by tracking launch times, battery draw, and camera latency across a set of representative devices.

Establish pre‑migration baselines for cold and warm app launches, typical battery usage during normal sessions, camera startup latency, and boot‑adjacent flows. After enabling larger page size support, rerun the same tests and compare results.

Observed outcomes: faster app launches up to 30% (about 3% average), battery savings near 4.56%, quicker camera starts between 4.48% and 6.60%, and boot improvements around 0.8 seconds.

  • Attribute gains to lower MMU overhead and fewer TLB misses, which improve system responsiveness on many devices.
  • Use consistent device sets (both 4 KB and larger page configs) so results isolate the page size effect from other variables.
  • Track memory usage alongside performance so net user benefit is clear for product teams.
MetricBaselineObserved gain
Cold app launches1000 ms~3% faster (avg)

Conclusion

, A timely migration protects releases and turns an optimization into a compliance win for developers.

Google Play enforces that updates targeting Android must support the 16 KB page size from November 1, 2025, so teams must act now to avoid blocked uploads and lost visibility.

Practical steps: upgrade Android Studio and AGP, move to NDK r28+, remove fixed page assumptions, rebuild native modules, and validate artifacts across both page size configurations with APK Analyzer and Lint.

Benefit: properly aligned artifacts run on both 4 KB and larger page installs, improving page tables efficiency and lowering runtime overhead for a smoother user experience.

For planning, audits, build changes, and vendor coordination, contact www.iottive.com or sales@iottive.com. This migration is a strategic investment in compliance, performance, and long‑term resilience.

FAQ

What changes on November 1, 2025?

Google Play requires that new submissions and updates targeting Android 15 or higher package native binaries with 16 KB page alignment. This affects apps that include native C/C++ libraries, game engines, or third‑party SDKs. The goal is better runtime performance, faster cold starts, improved camera responsiveness, and lower battery drain.

Why move from 4 KB pages to 16 KB pages?

Larger page granularity reduces page table entries, cuts TLB pressure, and improves I/O and memory mapping behavior. That translates into quicker launches, faster boot paths, and smoother camera handoffs on modern silicon. It also aligns with the system’s default runtime optimizations in Android 15.

Which binaries are in scope for the deadline?

Any native library (.so) packaged inside an APK or AAB must be aligned for 16 KB pages when the app targets Android 15+. This includes third‑party SDK modules, game engines, custom native code, and bundled runtimes such as those used by React Native, Flutter, Unity, or Unreal.

How do I find native modules that need changes?

Use APK Analyzer or unzip the package and inspect lib/ for .so files. Search source trees for PAGE_SIZE or hardcoded 4096 values. Static analysis and simple scripts can flag mismatches, and Android Studio tools list packaged native artifacts for review.

How should I handle hardcoded page‑size constants?

Replace literal 4096 values with runtime queries such as getpagesize() or sysconf(_SC_PAGESIZE). Audit code paths that assume alignment for mmap, custom allocators, or shared memory and refactor them to be page‑size agnostic.

What toolchain versions enable 16 KB packaging?

Use Android Studio with AGP 8.5.1 or later and Android NDK r28 or newer. Older NDKs can sometimes be made compatible by adding linker flags, but rebuilding all native modules with the supported toolchain is the safest approach.

Do I need to rebuild third‑party SDKs I don’t control?

Yes. If a vendor supplies prebuilt .so files that assume 4 KB, those artifacts must be updated. Coordinate with SDK providers and check their release notes for 16 KB‑ready binaries. For engines like Unity or Flutter, monitor official channels for compliant builds.

How can I test compatibility locally?

Run emulators configured for 16 KB page targets, test on real devices (Pixel devices expose getconf PAGE_SIZE via adb shell), and use remote device labs like Samsung Remote Test Lab for broader coverage. Validate cold starts, camera launch, and mmap behaviors under both 4 KB and 16 KB environments.

What CI checks should I add?

Add lint rules and scripts that detect non‑aligned libraries, hardcoded 4096 constants, and PAGE_SIZE misuse. Fail builds that include offending binaries. Integrate APK Analyzer steps and automated on‑device smoke tests to catch regressions early.

How do I verify binary alignment?

Use build outputs and readelf/objdump to inspect segment offsets and alignment. Packaging tools in AGP will report alignment status; you can also write small scripts that check file offsets within the AAB/APK for divisibility by 16 KB.

Will supporting larger page sizes improve battery life?

In many cases, yes. Reduced page table activity and fewer TLB misses lower CPU overhead, which can cut power usage during heavy memory operations. Gains vary by workload, device, and whether the app uses native code heavily.

Are there known runtime risks after switching page sizes?

Risk areas include allocators that assume page granularity, misaligned mmap offsets, and hand‑rolled memory pools. Unchecked assumptions can cause crashes or subtle corruption. Thorough testing and replacing fixed constants with runtime queries mitigate these risks.

What’s the recommended rollout plan?

Assign owners and deadlines now, inventory native code and SDKs, upgrade toolchains, rebuild native modules, run device and emulator tests, and gate CI to block non‑compliant builds. Coordinate vendor updates for third‑party libraries and communicate timelines internally.
